Russia (bbabo.net), - With the advent of "omicron", experts again remind about the importance of revaccination. Booster vaccination should be done six months after the first vaccination or previous COVID-19.
As for the choice of the drug, here the recommendations of experts may differ, and, accordingly, the people begin to doubt what to inject this time.
According to the recommendations of the Russian Ministry of Health, a booster vaccination can be done with "any vaccine registered in Russia." In Moscow, for example, they record on a booster at the request of a person - you can choose "Light", you can use the full "Sputnik V".
Much also depends on the individual characteristics of the human body. If, for example, he underwent the first vaccination with complications, the doctor may recommend another drug for re-immunization (in addition to the Sputnik family, two more vaccines are registered in Russia - EpiVacCorona and KoviVac, although their production volumes are significantly inferior to the Gamaleev drug, and therefore these vaccines are not always available and not in all medical institutions). Nevertheless, in practice, single-dose Sputnik Light is usually recommended for vaccinated Sputnik V. Although, for example, the head of the Gamaleya Center, Alexander Gintsburg, said the other day that for the elderly over 65+, taking into account the arrival of Omicron, it is better to perform the second vaccination with a two-dose Sputnik V.
Oksana Drapkina, chief freelance specialist in therapy and general medical practice of the Russian Ministry of Health, told who needs a booster in the first place. “A booster vaccination according to the recommendations is appropriate for everyone, but first of all, it is necessary to protect the most vulnerable groups: these are the elderly, people with chronic diseases, patients with arterial hypertension, obesity, and diabetes mellitus. That is, these are those groups of citizens who have new coronavirus infection can be severe," the chief specialist said.
She also recalled that booster vaccination, including by the elderly, is well tolerated.
"Booster vaccination is carried out with the same vaccines as vaccination, so it is as effective and safe as vaccination. From experience, most often we see that booster vaccination is well tolerated. Vaccine developers describe that Sputnik V is active against new strains. I quote what the scientific team of Alexander Leonidovich Gunzburg says," Drapkina emphasized.
Booster vaccination leads to a sharp increase in the level of protective antibodies to the SARS-CoV-2 coronavirus, but also enhances long-term T-cell immunity, experts say. With each subsequent vaccination, the quality of antibodies improves, noted the famous virologist Konstantin Chumakov.
